METHODS
This study evaluates the Delaware Cancer Registry’s 2014 breast cancer data using BCSRT, a CoC CP3R quality of care measure therapy was administered within one year (365 days) of diagnosis for women under age 70 receiving breast conserving surgery
for breast cancer.” The clinical rationale for this measure, as
evidence from randomized clinical trials that radiation therapy reduces the risk of local recurrence in the breast and may have a 5
Analytic breast cancer cases diagnosed in 2014 were selected from the Delaware Cancer Registry database using the CoC’s BCSRT case eligibility criteria. Breast cancer cases were examined. The two groups for race were White and Other regardless of Hispanic ethnicity. Differences in continuous variables (age and time to radiation) were examined using a
(whether the case had radiation, having radiation within 365 days, and vital status) could not be assessed.
RESULTS
An in-depth review of the 307 cases selected showed that
42 cases were missing radiation treatment data (14 percent of the total). Research was conducted in the Delaware Health Information Network (DHIN) to obtain radiation treatment data for these
cases. Of the 42 cases, radiation data was not found in the DHIN for 12 cases, and hospital cancer registries were then queried for information. Results are shown in Table 1.
the Other group compared to Whites. One patient did not meet the “within 365 days guidelines” for radiation (this patient received radiation at day 390). DHIN research revealed that patient’s
